correspondent savannah guthrie is here with us in our new york studios with more on this to start us off. >> reporter: as is customary in washington, colbert submitted prepared written remarking before his testimony, and they looked straightforward enough. when he sat down to testify, he went off script and into his comedy routine. and not everyone is laughing tonight. on capitol hill today, more evidence of why some americans think washington is a joke. the comedian stephen colbert, was billed as an expert witness on farm labor. and testified in character. >> congresswoman asked me to share my vast experience, spending one day as a migrant farm worker. i'm happy to use my celebrity to draw attention to this important complicated issue, and i certainly hope that my star power can bump this hearing all the way up to c-span1. >> reporter: one congressman initially asked him to leave. >> you run your show, we run the committee. but what do you say to that, stephen? >> reporter: but the testimony went on for several uncomfortable minutes. though not every member gave him undivided attention.
